It's happened to the best of us: your coffee slops over the edge of the cup when you add cream, or your leaky tea pot leaves a puddle on the table top. While most of us would mop up those messes, Jenny McMaster actively seeks them out. She then transforms those stains into maps. Her new exhibit "Private Sea and Social Tea Maps" is on-view this weekend at Blink Gallery. She dropped by the studio to tell us about it.
